Twelve Foot Ninja are an Australian rock band formed in 2008. Each song on their 2012 debut, Silent Machine, comes with a comic about a 12-foot ninja and inspired by the songs’ lyrics. Their first headline tour sold out every major city in their native country, and now they are coming to the States. The group will be playing at the North Star Bar in Philadelphia on May 6 and at The Studio At Webster Hall in NYC on May 12.
